WorksheetsEvaluating Interface Designs: Introduction
Total questions: 20
Worksheet time: 10mins
A team must allocate evaluation costs between 20% and 5% of the project. Which factor would most directly shift the allocation toward the higher end?
Late design stage with low risk
Fixed timeline with stable scope
Experienced team with mature process
Early design stage with high criticality
Which statement best describes a core goal of heuristic evaluation in interface design?
Measure user satisfaction with long field surveys and diaries
Verify conformance against a short list of design principles
Quantify business impact using revenue and conversion metrics
Simulate real usage by recruiting many novice participants
In a formal usability inspection, what is the primary role of the moderator or judge?
Defend the design from all criticisms raised
Recruit participants from the target market
Collect quantitative metrics from lab instruments
Facilitate structured discussion of merits and weaknesses
In discount testing, the typical rationale for small samples is that
diminishing returns reveal most issues early
regression models need minimal data
ethnographic depth replaces numbers
legal compliance limits recruitment
Which statement distinguishes formative from summative evaluation?
Formative uses large samples; summative uses small samples
Formative guides redesign; summative validates outcomes
Formative produces metrics; summative creates hypotheses
Formative is competitive; summative is discount
A team designing a complex medical dashboard should avoid relying solely on discount testing because
only summative data finds usability issues
discount methods ban clinical domains
discount testing cannot use prototypes
more participants are needed to test complexity
Which planning action best supports fair comparisons in competitive testing?
Create matched tasks across products
Hide timing metrics from observers
Randomize all interface labels
Recruit only expert users for speed
Why might competitive testing sessions run longer per participant?
Post-test training is mandatory
Setup requires multi-camera rigs
Each person tries multiple interfaces
Pre-test surveys are extensive
What network consideration is central to universal usability testing?
Performance on both slow and fast networks
Latency on fiber networks only
Airplane mode behavior for safety
Throughput under satellite throttling
Field tests primarily place new interfaces in what setting?
Realistic environments for a fixed period
Controlled lab rooms without time limits
Crowdsourced sessions with no oversight
Synthetic benchmarks on virtual devices
What is a benefit of portable usability labs?
Unlimited lab participants without cost
Automatic bug fixing during sessions
Videotaping and logging facilities on the go
Replacing the need for consent forms
What trade-off occurs when users test on their own equipment?
Elimination of all privacy concerns
Guaranteed uniform performance metrics
More control and richer in-person observation
Less control and fewer observation opportunities
When deploying a beta, what should a team plan for?
Feature freeze for several years
Identical hardware for all testers
In-person interviews for every user
Feedback management at large scale
Which choice best links method to strength?
Portable labs: replace all logging needs
Field tests: full control of every variable
Remote testing: scale and diversity at lower cost
Universal tests: ignore old devices entirely
A team must ensure performance for commuter trains and offices. Which approach is most suitable?
Only desktop lab sessions on wired ethernet
Remote testing with identical high-end laptops
Field tests without any logging software
Universal testing across slow and fast networks
Why are written user surveys a strong companion to usability tests and expert reviews?
They ensure zero bias across all responses
They replace the need for any observation
They measure only interface feature counts
They collect large samples offering authority
For background data, which item complements age, gender, and education?
Origins information
Vision acuity
Marital status
Political views
Which data point could explain low adoption despite adequate training?
Office lighting is warm
Team has many interns
Workplace lacks parking
Interface too complex
What outcome dimension contrasts bored with excited?
Task completion rate
Error severity index
Cognitive load score
User affect after use
Which example reflects printing as a surveyed capability?
Organizational structure map
Affective response measure
Background demographics set
Feature familiarity category
